[quote user="Vasyachkin"]things should be PERFECT at least in theory.[/quote] For stereo systems, we start with two small microphones with strictly limited ability to capture an acoustic musical event at a particular combination of phases, reflection...

You might want to try covering a section of plywood with the modified cement/mortar recipe as a test before you write it off as too difficult or too expensive. Basically, it does pretty much what you ask, and it need not be 2" thick, either; 1/2" or...

[quote user="noviygera"]I feel that the best candidates are metal springs. 1. They won't compress or deteriorate quickly.2. They work good in the used freq. range.3. Easy to replace. Easy to tune by adding or removing springs.4. Easy to float the ent...

I pretty much know what I need to do – I need to go for shaper filter built in my power amp. The second order I have no is too impactful to midbass, so I need to do for 2th order or perhaps for 4th and try to integrate it. Whatever it will be I thin...

Was invited over to Romy's today for a listen. In the last two days, he made several small but critical changes in the time alignment, crossovers, and room damping, and the sum of them has brought his system up by several notches producing the best a...

[quote user="rdrysdale"]Do you think it would be possible to find the proper location by using a smaller pair of speakers, and then substitute in the big horns? At least to get to a close position?[/quote]Absolutely not! The “points” or even the “zon...

[quote user="Romy the Cat"]
You see, in my view, what those smaller labels and big labels do in term up-closed microphones and artificial reverberation (even though it NEVER done properly) is something that event delivers a small tactical advantage ...

user="jackydai"]Romy, I’m disappointed to see you confront your own
belief just to win a debate. It is not my intention to convince you, but if
you, after all these years of research on horn flares, think that a twisted
flare rate at t...

Actually (probably because of the phase coherence and tight dispersion control) they sound very good even with some basic equipments, like the small 300 USD Parasound zAmp for example, but I like them most with the pro MC2 Audio MC1250 amps or the Fr...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

[quote user="be"]Gregm, you wrote: "Yet, the best result -- i.e. most homogeneous sonically -- came from the thinner wires in interconnects."Did you use silver wire for your comparison?[/quote]I used copper in my example above. Later on, I received r...

[quote user="drdna"]I would not restrict myself to the idea that things need to be a certain way or a certain configuration of the drivers or ports based on theory alone. I think it is important to ask what is interesting about the sound that the new...

[quote user="vuki"]Anyway, my plan was to make powerful triode NFBless amplifier for relatively small money. I'm really satisfied with what I did. Maybe I should have done GM70 SE, but what would be my next project then?[/quote] The GM70 is a bitch a...

Yes, all you said about the Fostex and heavy mouth MF seems reasonable. I don't know what's wrong, but I get the feeling that it's sort of hollow-sounding and could be much more loaded. I'll finish the horns completely before any final conclusions.In...

[quote user="Romy the Cat"]fiogf49gjkf0dWell, that is kind of the end of the little midbass era. As
we begin to prepare the moving in a month I removed the Vitavox driver from
Midbass horns. The even went unnoticed in my family but I have a lot in ...

Romy, I am not saying he should go all out on treatments yet but adjusting your playback with a problematic room is not an efficient route to take.
I guess we are on the same page Anthony. Before putting your speakers in the room, ha...

Hello, new to the forum... very glad to find it. I'm a sound guy at a small celtic/trad venue, I've had the opportunity to hear everything from Strads to FO Stanley's. I'm not professing to be an expert, I've just had the chance to listen to a good...

As a new concert season is coming up with BSO opening night next week I was sprucing up my recording studio. The machine is 3MHz with 2G memory – plenty run SoundLab5. The SoundLab just record and play, I do absolutely nothing else in this software, ...

[quote user="drdna"] Oh, I see you are absolutely correct. I am very puzzled. As it says on the website, the mastering studios relocated to a new location. Maybe there was no room for the old set-up. I was only in the old studio a few years ago. I sw...

I touched on local electricity problems in a recent electricity post. Briefly, the local nuclear plant has been shut down by concerned politicians after "leaks" were detected. Setting aside mutated flora and fauna, sound has been worse more of the ...

Well, I thought there was a lot of this going on all along, but that we just haven't come up with much that is "universal" in the usual, "what do you recommend?" sense yet? Maybe this is because one person's Cu PIO is another person's...

In my case, the Wright Sound WPA3.5s, with ~8 Watts on tap in A2, could not handle my 97 dB speakers; not because it was not loud enough, but because the distortion was too much of a factor too much of the time, and "bass" was bass-ically A...

Well, I do have 3 channels of DSEP. Dedicated Single Ended Pentode: one channel (bass/mid 30-500 Hz) with a 307A DH pentode feeding two wonderful Fane neodymium Colossus 12" - one from FS to 150 Hz and the second from FS to 500 Hz. OPT with a lot of ...

I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "my own" care, "my own" taste, ...

I think when we are taking about the today TT we do not mean inventions – there are no inventions that I see in mega-priced turntables. All that I see are small manufactures, very inefficient production, very little market for sale and distribution a...
